2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 62053. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 62053 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
IEC 60687:1992, Alternating current static watt-hour meters for active energy (classes 0,2 S and 0,5 S)
IEC 61036:1996, Alternating current static watt-hour meters for active energy (classes I and 2) IEC 61268:1995, Alternating current static var-hour meters for reactive energy (classes 2 and 3)
3 Definitions
For the purpose of this International Standard, the following definitions apply.
3.1 multi-energy meter meter which, in a s ingle case, measures two or three types of energies (watt-hour, var-hour, VA-hour)
3.2 multi-function meter basic or multi-energy meter which, in a single case, has functions that are not described in the basic standards for watt-hour, var-hour and VA-hour meters
NOTE — M ulti-function meters may include: maximum demand indicator, time switches, ripple control or radio receivers, pulse output devices, etc.
4 Requirements
4.1 Standard electrical values Refer to IEC 61036.
4.2 Name-plates
Refer to IEC 61036, with the following additions:
b) designation of type (see definition 3.1.4 in IEC 61036) ; each type of measurement performed (watt-hour, var-hour and VA-hour) shall be indicated;
I) the class index of each type of measurement (watt-hour, var-hour and VA-hour).
4.3 Power consumption
4.3.1 Voltage circuits
The active and apparent power consumption in each voltage circuit of a meter at reference voltage, reference temperature and reference frequency (see 5.1.1) shall not ex ceed the values shown in table 1.The figures in table 1 ar e mean values. Switching power supplies with peak power values in excess of these specified values are permitted, but it s hould be ens ured that the r ating of associated voltage transformers is adequate.
If the meter is operated with an auxiliary power supply, table 1 is not applic able and the maximum consumption of this power supply can be agr eed upon betw een the us er and the manufacturer. The consumption of each voltage circuit shall be less than 2 W and 10 VA.AS 62053.61 pdf download.
